Application. March 9, 1948; Serial No. 13,930

This invention relates to a trailer for hauling ay stack of hay 'andscattering the hay over large areas.

Et is necessary on largeicattle and sheep ranchesv during the wintermonths to scatter feed for the cattle and sheep over large, snow coveredareas in order to provide winter range feed. This is usuallyaccomplished by forking hay from a truck, but on large ranchesl thisbecomes an almost impossible task.

The principal object of this invention is to` provide a vehicle uponwhich `a complete hay sta-'ck may be loaded, and `to provide kpower'operated mechanism therein `which will automatically lfork the hay fromthe stack and distribute it in piles or windrows along both sides ofthepath of the vehicle.

Another object of the invention is to s o construct the device that itvmay be trailed behind any suitable truck or towing vehicle, andtoprovide a mechanism which will require no eXtra man power other than thevehicle driver.

Other objects and advantages reside- 'in the detail construction oftheinvention,y which is designed for simplicity, economy, and emcien'cy.These will become 'more apparent from the following description.

In the following detailed' description of thev invention, reference ishad to the accompanying drawing which forms a p'art'lhereof.Lilienumer.- als refer to like parts in all views ofthe drawing andthroughout the description.

The improved 'hay scattering trailer comprises a chassis Ill carried onrear wheels- H and lfront- 5 Claims.. '(Cl. 21k-3.16)

wheels l2. The chassis lll supports a. bed f3 for holding va stack ofhay, as indicated in broken line at |14.

A 'platform l5 extends forwardly from the chassis Hl atv a higherelevation than the latter and over the front wheels l2. The frame l 5carries a tiltable front axle frame i6 mounted on fore and aft tiltingpivots I'l.

A Ysteering spindle I8 is carried at each sideV of the frame I6, andeach spindle supports one of the front wheels I2. The twol spindles aretied together by means of a tie rod I9 so that the two wheels will guidein unison. A towing tongue 20 extends forwardly from a tow pivot 2l atthe'bott'om of the central portion of the Wheel frame IB.

An I'beam column 22 extends upwardly from each front corner of thechassis i5. columns 22 are connected across the top by means of a topVbeam v23 and are braced from a brace frameiV extending upwardly from theforward portion of the'platform l5.

Twover'tical'posts 25 extend upwardly from the forward edge of thechassis Ill to a connection with the cross beam 23. These posts arebraced fronithe brace frame' v24 by means of suitable cross braces 26to' hold the columns 22 rigidly vertical.

A slide tube or pipe 21 is supported rearwardly of each column 22' invertical, spaced relation therewith by means of a cap plate 28. Asliding sleeve 29 is mounted on each pipe 2l. Each sleeve 29 carries twoside frame plates es eX tending on opposite sides of the columns 22..

Each side plate 'carries a pair oi flanged rollers 64 which travel alongthe flanges of the I-'beam columns 22. The two sleeves 29' are securedtogether across the frame by means of a cross bar 30' so that they willmove vertically in unison. The 'cross bar 3G is supported by means offlexible cables 3| running over sheaves 32 to a winch drum 33 which isrotated from a suitable motor 34.' Thus, it :can be seen that the crossbeamen, the sleeves 29' and the side frame plates 63, can beraised andlowered along the guides 2l.

The motor 34 drives a speed-reducing mecha- 35 through the medium ofV-loelts 36. The speed `reducer drives a power shaft 31 which drives aclutch dog 40. The clutch dog 40 can he shifted back and forth to engageeither a transmission chain device 39,-for rotating the countershaft 38in one direction, or a reverse gear 41 for' rotating the counter-shaft38A in the other direction'.

` The-'countershaft 38' is operatively connected The two to the winch33. A clutch lever 42 extends to a convenient position for the operatorto control the operation and direction of the winch drum 33.

An operating crank shaft 43 extends between the sleeves 29 below thecross beam 39 and is provided with a sprocket 44 at one of itsextremities by means of which it is rotated from a drive chain 45. Thedrive chain extends from a drive sprocket 46 upwardly to an idlersprocket 41. The idler sprocket 41 is journalled at the top of one ofthe columns 22, and the sprocket 46 is iixed on a second counter-shaft48. A clutchl dog 49 is splined upon the second counter-shaft 48 so thatit may be brought into operative engagement with a sprocket driven bymeans of a drive chain 50 from the power shaft 31.

The chain 45 is trained around guide sprockets supported from the sleeve29 which guide it around the sprocket 44. Thus, it can be seen that theengine 34 will rotate the operating crank shaft 43 at all verticalpositions of the latter.

A cantilever truss frame 52 extends forwardly from each guide sleeve 29.The forward extremities of the two truss frames 52 are connected bymeans of a cross bar 61. A pivot plate 65 is secured to and extendsdownward from the lower member of each truss frame. The plates 65 areprovided with bearing openings which are tted over supporting studs 53projecting outwardly from each pair of frame plates 63. The studsprovide pivots for the truss frames 52 so that the latter may be tiltedupwardly and downwardly. The truss frames project forwardly from thepivot points and are connected by means of a cross frame 66 whichsupports a counter-weight 54. The counter-weight 54 is adjusted tosupport the major portion of the weight of and on the two truss frames52.

Two rotatable idler crank shafts 55 and 56 extend between the trussframes 52. All of the crank shafts are formed with a plurality ofadjacent cranks positioned 90 apart. A plurality of parallel rakemembers 51 extend between the cranks of the crank shafts 43, 55, and 56.Each rake member is formed in the shape of a light truss to increase thestrength and rigidity thereof and to decrease the weight. An endless tiechain extends about suitable chain sprockets 69 on al1 of the crankshafts so that they will rotate in unison in the same direction.

Each rake member 51 carries a plurality of inverted, V-shaped rake teeth58 at spaced apart intervals.

The trusses 52 support the rake members over the hay stack |4, and thecrank shafts rotate clockwise in Fig. 1 so that when at the bottom, therake members will move toward the columns 22, and when at the top theywill move away from these columns so as to constantly rake hay from thetop of the stack over the forward end thereof.

The hay falling over the forward end falls upon two conveyor belts 59,there being one belt extending outwardly at each side of the bed I3. Thebelts 59 are trained over rollers 60. The middle rollers 66 are drivenin opposite directions by means of intermeshed gears 6| driven from thesecond counter-shaft 48 through the medium of beveled gears 62. Thebelts 59 carry the hay outwardly to the two sides of the trailer anddeposit it in piles beyond the paths of the rear wheels A separatingplate is welded between members of the truss frames 52 immediately overeach of the supporting studs 53. The plates 10 are cut out as shown at1| in Fig. 9 for the pas'- sage of the drive crank shaft 43. The cutouts 1| are sufficiently large to allow the plates 10 to rock with thetilting movements of the cantilever trusses 52 without interfering withthe crank shaft 43.

Stub shafts 12 are welded or otherwise secured to the plates 10 andproject outwardly from the latter to rotatably support the idlersprockets 5|.

A tie chain or cable 14 extending from the forward cross frame 66 to aconnection with the brace frame 24. The length of the cable 14 is suchlthat, when the sliding sleeves are elevated to'their highest positionthis cable will tighten vto lift the rearward extremities of the trussframes to the position of Fig. 1.

When in theI latter position a stack of hay is loaded onto the bed 3.The trailer is then attached to a towing vehicle by means of the tongue20. The motor 34 is started and the clutch 49 is engaged to startrotation of the rake crank shafts and the conveyor belts 59. place forscattering the hay is reached the clutch 40 is engaged to unwind thecable from the reel 33.

The sliding sleeves now gradually move downwardly slackening the pullcable 13 and allowing the rake teeth 38 to rest lightly on the stack |4,the weight being controlled by the counterweight 54. The rakes rake thetop hay in piles onto the two conveyors 59 which scatter it at bothsides of the trailer.

While a specific form of the improvement has been described andillustrated herein, it is desiredl to be understood that the same may bevaried, within the scope of the appended claims, without departing fromthe spirit of the invention.

Having thus described the invention, what is claimed and desired securedby Letters Patent is:
